Amnon Heiman 6e1f042b93 storage_proxy: use time_estimated_histogram for latencies ...

This patch change storage_proxy to use time_estimated_histogram.

Besides the type, it changes how values are inserted and how the
histogram is used by the API.

An example how a metric looks like after the change:
